Underwater weeding device

Abstract

The invention discloses an underwater weeding device. The device comprises an underwater moving platform; the lower end of the underwater moving platform is provided with an execution mechanism module, the execution mechanism module comprises a cutter head upper cover and a cutter head base, a speed reduction motor is fixed in the cutter head upper cover, and a central gear is connected to the output shaft of the speed reduction motor through a motor flange and installed in the center in the cutter head base; a plurality of driven gears are also fixed in the cutter head base and evenly distributed at the outer side of the central gear, and the central gear is meshed with the driven gears; each driven gear is fixedly provided with an eccentric shaft, each eccentric shaft is sleeved with a connecting rod, a movable shaft is connected to the other end of each connecting rod and slidingly arranged in a guide rail, and the guide rail is fixed in the cutter head base; each movable shaft is further fixedly provided with a cleat-shaped cutter which extends to the exterior of the cutter head base; the cutter head base is further fixedly provided with a plurality of fixing shafts for fixingthe cleat-shaped cutters.

Description

technical field [0001] The invention relates to the field of underwater weed cleaning, in particular to an underwater weeding device. Background technique [0002] At present, with the increase of pollution from agricultural planting, aquaculture, and domestic discharge, the phenomenon of eutrophication in water bodies is becoming more and more obvious. Whenever summer comes, all kinds of aquatic plants in irrigation and drainage channels and water areas grow wildly and spread, and this growth rate far exceeds that of aquatic plants. The flooding of aquatic plants will block the channel on the one hand, reduce the water passing capacity of the channel, and at the same time affect the water quality and pollute the environment; the removal of underwater aquatic plants mainly depends on manual removal. It is extremely fast, and the workload of removing underwater weeds is huge, and the expected effect cannot be achieved by manual work. At present, the underwater weeding device...

Problems solved by technology

The flooding of aquatic plants will block the channel on the one hand, reduce the water passing capacity of the channel, and at the same time affect the water quality and pollute the environment; the removal of underwater aquatic plants mainly depends on manual removal. It is extremely fast, and the workload of removing underwater weeds is huge, and the expected effect cannot be achieved by manual work. At present, the underwater weeding devices on the domestic market are large in size, low in efficiency, and not strong in practicability, so they are not suitable for underwater weeding in narrow rivers. Next homework

In response to this situation, the countermeasures still mainly rely on manpower to use tools with a low level of electrification to carry out weeding operations. This kind of countermeasure is costly and inefficient. The market urgently needs a new and efficient mechanized device to complete the underwater weed removal work.
